T0 aZZ wlwm z't may concern:

Be it known that I, MAURIGE G. ]?U SSEU, a citizen of the United States, res1dmg at Los Angeles, in the oounty of Los Angeles and State of California, have mventc d new and useful Improvements in Umv ersal Joints, of which the following is a spemfication.

This invention is a universal joint and has for its object the provision of a Construction wherein the two members of the oint may be readily assembled and taken apa rt and which, when in assembled relation, W111 be positively locked against dmassembly.

The invention Will be readfly understood from the following descript on of the accompanying drawings, in vvlnch Figure 1 is a aide elevatmn, partly broken away, of a joint constructed in accordance with the invention.

Fig. 2 is a plan view of the same also partly broken away.

Fig. 3 is an en VlGW of the convex and the concave members of the oint d1sassembled.

Fig. 4 is a side elevatmn of the members comprising the joint When taken apart and showing the relative position of the parts ready to be assembled.

Fig. 5 is an end Fig. 4.

The improved universal joint compr ses a concave member A and a co-operatmg convex member B, the two parts of the joint being shown as secured to the ends cf suitable shafting C. The concave member of the joint comprises a shell havmg a socket 1 at one end of the shell and a concave surface 1 on said shell and at right angles to the axis of the socket 1. and s hafting C. This concave surface is sphencafly curved so as to conform to a portion of the surface of the sphere comprising the convex member of the joint. The rim of the shell forming the concave surface is provided with inwardly projecting rims 2 and 3 arranged at opposite sides Of the rim of the shell and spaced apart by the diametrically opposite guideways 4. The inner por tions of these rims are curved, as shown at 5, to provide a scat for the concave member of the joint.

The convex member of the joint coinprises 3. sphere 6 having the socket 6 proelevation similar to beyond the rims 2 and 3 jectiug therefrom and arranged to engagarranged to be shafting C. The sphere is received against the curved surfaces 5 of the rims of the concave member of the joint so that the sphere may be revolved in all directions upon the scat thus fonned in order to provide a universal joint between the concave and convex members.

The means for locking the sphere upon its scat comprises a rib 7 extending partially around the sphere and having its outer surface 8 curved so as to be received against the concave surface 1 of the concave member of the joint. This rim is of such width as to extend through the guideways 4 and is of a suitable length to project when .the joint is assembled. The ends of the rims 2 and 3 at the at 9 and the sides of the rim 7 are similarly under out as shown at 10 so that when the rim is positioned within the guideways the co-operating undercut surfaces Wi1l prevent longitudinal displacement of the members of the joint relative to one another.

The two members Of the joint can only be disassembled When thus united by rotating the convex member of the joint relative to the concave member so as to slide the rim 7 lengthwise through the guideways 4. The rim 7 is pivoted to the sphere 6 at diametrically opposite points upon said sphere, so that the members of the joint may be universally shifted after the parts are assembled with the rim 7 locked within the guideways of the concave member.

The pivotal mounting for the riin 7 may comprise pins 11, preferably, enlarged heads 12 for retaining the pins in position, the pins extending through the rim and into the sphere 6.

The parts being constructed, as above describe and it being desired to connect the two members of the universal joint, the rim 7 is turned upon the sphere 6 until the axis of the connecting socket 6 is at right angles to the circumference of the rim 7 as clearly shown in Fig. 4. When in this position'the rim may be readily slid through guideways 4 by turning the sphere 6 upon the axis of the socket 6. When the rim has been slid so as to extend entirely across the concave member of the joint and so as to extend beyond both guideways 4, the members of the joint guideways 4 are under cut as shown provided with axis of the socket 6 an before the rim 7 is moved relative to the concave member a sufiicient distance to be disehgaged from the locking connection formed by the guideways 4:.

The joint, as thus assembled, forms a 11mversal joint, the sphere 6 being turnable upon the seats 5 to extend the axis of the socket 6 in any desired direction relative to the axis of the socket 1. When it is desired to separate the parts of the 'oint it is only nessary to swing the axis 0 socket 6 at right angles to the rim 7, and then by turning the convex member upon the axis of socket 6' the rim 7 Will readily slide across the concave surface 1 and out of the guideways 4.

Various changes may be made without de parting from the spirit of the invention as claimed.

What is claimed is:

1. A universal joint comprising a concave member and a herical member arranged to scat against sa1d concave member, and a dovetailed locking rim extending around a rtion of said sphere and pivoted thereto atiametricafly opposite points, said concave member having a locking guideway correspondingly dovetailed and ananged to receive sa1d loc rim, said locking rim being slidable into said lockng gnideway by turning said locking rim upon said sph;re until its circumferenoe is at right angles to the axis of said spherical member of the joint and then rotating said spherical member upon said axis.

2. A universal joint oomprising a concave member having retaining rims upon the rim thereof and spaced apart to form diametricaly opposite guideways, the surfaces of sai rims being curved to form a universal scat and a spherical member arranged to be received against said scat and having a Jocking rim extending around said sphere and pivoted thereto at diametficafly opposite points, the edges of said locking rim and said guideways hein undercut whereby said locking rim may %e locked within said guideways.

3. A universal joint comprising a concave member having retaining'mns upon the rim thereof and spaced apart to form diametrically opposite guideways, the surfaces of said rims being curved to form a universal seat and a spherical member arranged to be received against said seat and having a looking rim extending around said sphere and pivoted thereto at diametricaily opposite points, said pivotal mountin of the locking rim being so arranged that y tuming said spherical member until its axis is at right angles to the circumferen of said rim, the rim may be slid into said guideway by rotation of said sphericai member upon its axis, the edges of said locking rim and said guideways bein% undercut Whereby said locking rim may e locked within said guideways.

En testimony whereof have signed my name to this secification.
